8 Claims.

The present invention relates to a liquid dispensing device which is adapted to receive a sealed receptacle or can containing a, liquid to be dispensed and which it also adapted to receive and hold the liquid from the receptacle, the invention having particular reference to a can opening element which produces a pouring opening in an end of the can and at the same time so mutilates the body of the can that its reuse or its subsequent spurious use as a container for liquids is prevented.

An object of the invention is the provision of a liquid dispensing device having a single opening and mutilating element which operates to produce an opening in an end of a can inserted into the dispenser for draining the can contents into the dispenser and which simultaneously opcrates to mutilate an adjacent side wall of the can so that the latter cannot be again used as a receptacle for liquids.

Another object is the provision in such a liquid dispensing device of a can opening and mulilating element which is constructed of one piece and formed toshift the can relative to the ele ment when the cam is inserted into the dispenser to effect a positive and simultaneous cutting away of at least two adjacent walls of the can so that the can will be destroyed beyond repair for reuse as a container of liquids.

Another object is the provision of a liquid dispensing device having a can opening element of the character described wherein a single pressure applied on an inserted can causes the latter to move vertically down into the dispenser over the opening element thus opening the end of the can and at the same time causes the can to move laterally in the dispenser while mutilating a side wall of its body.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

Fig. 8 is a section of a lower corner of the can adjacent the mutilation showing also how the bottom of the can is out through by the cutter during the opening operation, the view being taken substantially along the line 88 in Fig. 7.

As a preferred embodiment of the invention the drawings illustrate a device which is adapted to dispense lubricating oil such as used in automobiles. The device mainly comprises a can opening and mutilating element or'cutter A (Fig. 1) and a dispenser or cutter supporting member B which is adapted to support the cutter. The dispenser B is also preferably adapted to re ceive a cam C to be opened and to co-llectand hold the contents of the cam after the latter is opened.

The dispenser B is similar to dispensers now commonly used in oil and gasoline stations and in garages for dispensing lubricating oil into automobile crank cases and the like. It comprises a cylindrical body I I (Fig. 1) open at its top end and having an upper outwardly curled or rolled edge l2 extending around the top rim. A similar curled or rolled edge l3 extends around its rim at its lower end.

A bottom I4 is secured within the body H and is preferably of an inverted con-e shape having a discharge pipe 16 which projects through a side wall of the body. The discharge pipe is con nected to one end of a flexible hose or tube l1 having atits opposite end a discharge spout 18 for dispensing the contents of the dispenser B. When the discharge spout is in non-discharging position it is supported in an upright position alongside the body wall by a hook I9 which is Secured to the curled edge l2 of. the body.

A handle 2| is provided for carrying the dispenser. This handle is secured by upper and lower rigid straps 22, 23 to a side wall of the dispenser body preferably in a position directly opposite the discharge spout l8 and hose IT.

The cutter A is disposed inside of the dispenser B adjacent its upper open end. It is supported on a side wall of the body preferably adja cent the discharge spout l8 and hose H. The cutter in cross-section is shaped similar to the letter B having a curved body wall section 25 (Figs. 2, 3, 4, and 6) which is secured by screws 26 to the dispenser body The ends of cutter body wall section 25 merge into inwardly curved wall sections 21, 28 which meet substantially in a vertical central plane, the traces of which are indicated by a line xa: in Fig. 6. Curved wall sections 21, 28 merge into straight wall sections 29, 3| which are contiguous and parallel. These straight wall sections extend back along the center line above mentioned and toward the body wall section 25.

The upper edges of the curved wall sections 2?, 28 are curved upwardly as at 32, 33 (Fig. 5) and are beveled on the inner faces as at 34 (Figs.

. 3 and 4) to provide sharp cutting edges for the cutter. The upper edge of the straight wall section 29 is curved downwardly as at 36 (Fig. 3) and is preferably beveled off in a sharp cutting edge. The upper edge of the straight Wall section 3| is inclined upwardly as a continuation of the edge 33 of wall section 28 and is beveled on its inner face to form a sharp cutting edge 31.

Cutting edge 31 terminates in a sharp spear shaped cutting element 38 which is disposed adjacent the body wall 25. This spear shaped cutting element projects beyond the terminal edge of the straight wall section 3|, the latter being cut back or relieved as at 39.

In the can opening operation the spear shaped cutting element 38 of cutter A cooperates with a stationary cam 43 having an inclined cam edge 44. Cam 43 is formed on an inwardly bent upper portion of the curved body wall 25. The cam is directly in line with the straight wall section 3| and extends under the spear shaped cutting element 38 and into the recess 39 with its cam edge 44 in spaced relation to the terminal edge of the straight wall section.

A can to be opened is inserted endwise and in vertical position into the top open end of dispenser B with the bottom of the can resting on the spear shaped cutting element 38 as shown in Fig. 1, the point of the cutting element being disposed adjacent the can end seam. By applying a downward pressure on top of the can the latter is forced down over the cutter.

As the can descends the spear shaped cutting element 38 first punctures the can bottom adjacent its end seam as shown in Fig. 4. Simultaneously with this puncturing action the can end seam engages against and slides along the cam edge 44 of cam 43. This shifts the can sidewise or transversely of the dispenser as the can moves further down over the cutter causing the spear shaped cutting element to also puncture the adjacent vertical side wall of the can. The puncturing of both can bottom and. side wall is done almost simultaneously and at the very beginning of the can opening operation.

then cut into the can bottom wall severing the latter along a B shaped line 45 (Fig. 6). This produces a large opening 46 in the can bottom through which the contents of the can drains out into the dispenser. The cut away portion of the wall is turned back as at 41 (Fig. 8) to permit rapid draining of the can. 1

During this opening or can bottom severing operation the sharp upper edge 31 of straight Wall section 3| continues to elongate the slit cut into the side wall of the can. This action finally produces a long slot 49 (Figs. 3, '7 and 8) which irreparably mutilates and destroys the can body for subsequent use as a container of liquids.

The can comes to rest with its lower seam seated against the bottom walls of notches 5| which are provided in the upper edges of the curved wall sections 21, 28. The seam also seats against a right angle stop 52 which is secured by a screw 53 to the dispenser body on a wall opposite the wall on which the cutter is mounted. This lowermost position is shown in Fig. 3 and in dotted lines in Fig. 1. When the liquid is fully drained from the can into the dispenser it may be poured out in the usual manner through the dispenser discharge hose H and spout l8.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
